For pyromaniacs on the mend (or rise), Little Inferno might seem like a dream come true, as the oddball iPad app allows players to burn more than 100 distinct digital items within a virtual fireplace free of soot and real-world ramifications. For everyone else, the simple and repetitive act of buying items and using your finger to set them ablaze might initially seem pointless, but a mysterious back story, ample style, and a dollop of humor keep this compelling curio interesting long enough for it to show what's beyond the somewhat banal interactions.
